To mil II'II/OIIZ/ it puny concern.-

Be it known that l, GUSTAV Fnunknna subject of the German Emperor, residing at Delmenhorst, Germany, have invented certain new and useful Improvements in Machines for Mann facturingLinoleum,of which the following is a specification.

The said invention relates to a machine or apparatus for manufacturing linoleum in which the pattern extends through the material; and the object of theinvention is to provide a simple, economical, durable, and effective machine capableof producing linoleum in as rapid a manner as possible and at a low cost.

To this end the invention consists, broadly, in a machine or apparatus for applying granular material to a supporting or backing strip having means for moving the backing strip or sheet intermittently and a stencil-plate with means for moving it with the backing-sheet and raising it and returning it to initial position while the sheet is at rest.

The invention further includes the various features of construction and arrangement of parts, as hereinafter described, and particularly pointed out in the appended claims, which fully and clearly define the invention and distinguish it from the state of the art.

The invention is illustrated in the accompanying drawings, in which Figure l is a longitudinal vertical section through the center of the machine. Fig. .2 is a plan view, partly in section. Figs. 3 and T are detail views. Fig. 5 is an enlarged sectional view with parts omitted. Fig. 6 is a sectional view of the wheels 0.

Referring by reference characters to the figures, in which the same parts are designated by the same letters throughout the several views, the driving-shaft to which the power is transmitted for operating the machine is shown at 1/. This carries a beveled gear 7/, which engages with a beveled gear I) on a shaft (3, longitudinally disposed centrally of the machine, which at its opposite end carries a beveled gear 7f, meshing with beveled gears If and 1/, loosely journalcd on a shaft 1,, which through connections hereinafter described operates to reciprocate the stencilplates t. The beveled gears I) and 7) are both loose upon the shaftu and are designed to be alternately clutched to the shaftby a clutch member-f, having frusto-conical friction-disks (Z and (7, which engage with corresponding recesses in the gears 7) and 7), and which may have their friction surfaces covered with leather or any otherapproved material for assisting in procuring the frictional engagement.

The clutch member f is operated automatically to engage first one gear and then the other, and thereby automatically reciprocate the stencil-plates,by means of a cam r mounted on the shaft 0, which engages a roller 1', carried by one arm of a bell-crank lever 71/, secured on a shaft 0, the opposite arm being provided with a weight '4 by which the roller is held constantly in contact with the surface of the cam This shaft 0 also carries an arm /1., which is provided with rollers la which engage or rest in the groove of the clutch, so that as the cam y rotates the arm ll will be rocked and the clutch f accordingly thrown into frictional engagement first with one gear and then with the other.

The Sllflftc carries at its opposite ends drums Zr, upon which are wound and secured the end portions of bands (1 and 0 The bands 0' lead rearwardly around an idle pulley 1'1, and connect with a cross-bar which has its end portions resting in vertical slots z of brackets 23, which are secured to bars 2 which support the stencilplates. The bands a lead forwardly from the drums and passing around a pulley or wheel a are secured in their turn to the front sides of the bars These bands 0' are preferably provided with projections n, which engage in corresponding recesses 0 in the peripheries of the wheels, whereby the bands and wheels are caused to move in unison. It will thus be seen that as the shaft (1 is operated in the manner described the bands 1/ and 0 will be alternately wound and unwound upon the drums K, with the result that the cross-bar will be caused to travel back and forth in the guiding-recess m of the frame, and through its connection with the rails r" by the brackets above referred to the rails will be reciprocated longitudinally of the machine and with them the stencil-plates Z.

In order to move the backing-sheet forward while the stencil-plates are moving forward and to hold it stationary while the stencilplates are being carried back to an initial position, I provide on the shaft 0 additional pulleys 0r wheels, over which pass bands p, these bands passing at the rear of the machine over idle pulleys C, which are preferably mounted in adjustable bearings, so that any slack in the bands may be taken up. These bands likewise have projections which engage recesses in the driving-pulley, whereby slipping is prevented in the same manner as by the projections and recesses 0 and 0 already referred to. The wheels upon which the bands travel and by which they are driven .are provided with bosses or projections 0" within the peripheral rimof the wheels 0, to which are pivotally mounted clutch-arms 0, so arranged that on the forward movement of the parts in the direction of the arrow the clutch members 0 will be engaged by the wheel 0, and consequently the wheels around which the bands 1) pass will be rotated. On the backward movement of the cross-bar Z and its bands the clutch-arms 0 will be disengaged, whereby bands 12 will be held stationary. It will of course be understood that the backing-sheet upon which the granular material is laid or deposited by the stencil-plates is carried by these bands p.

It will be obvious thatit will be necessary to raise the stencil-plates above the sheet of material while they are being moved backwardly. To provide for this and to enable their being more easily moved, I mount them upon antifriction-bars 6 which are carried by arms a, mounted on rock-shafts which are rocked by an arm (6 operated in turn by suitable connections (indicated at a from the shaft a.

At the beginning of the operation the stencil-plates rest upon the backing-sheet and move forward in unison therewith in the direction of the arrow .2, Fig. 1. During this time the stencil-plates receive the granular material from the troughs 1', which are held against longitudinal movement, and consequently deposit the material in an even layer upon the stencil-plates as the latter move for ward. In order to cause a more even distribution of the material, each trough is provided with a grid 8, having cross-pieces s, and which is reeiprocated transversely of the machine by an eccentric connection with the shaft a. The troughs or hoppers r are held against movement by U-shaped brackets a, which engage bosses on the shaft u. The grid .9 is preferably guided by antifrictionrollers r and r carried by the trough 0". It will be understood that in Fig. 1 the stencilplates are supposed to be at the limit of their forward movement and about to be reversed. After the backing-sheet, with the granular 5 material deposited thereon, leaves the conveyer-bands p it is passed through a suitable press a in order to receive a preliminary pressing and is then wound upon a cylinder or roller 3 which of course must be operated intermittingly in unison with the remainder of the machine.

Having thus described my invention, what I claim is 1. A machine for applying a granular covering material to a backing-sheet, comprising means for moving the backing-sheet, intermittingly, and a stencil-plate with means for moving it with the backing-sheet and raising it and. returning it to initial position while the sheet is at rest.
